Simple tu lèves l'arrière de la mx pour décoller les deux roues, puis tu tournes une roue.
Si les deux tournent dans le même sens c'est un LSD si elles tournent dans le sens contraire c'est un differentiel simple.

Pas nécéssairement. Avec un Torsen, les 2 roues tournent dans le sens contraires... Comme si c'était un open

I have a 96 Miata. I've read on the web that this year's model comes
with either an open or Torsen differential.


With my car on stands, when I spin the one rear wheel, the other wheel
will spin in the opposite direction. When I hold one of the wheels
tight, my son was not able to spin the wheel on the other side. Can
anyone conclude from this rather I have a Torsen LSD or not? If not,
is there any other test I can do short of pulling off a stub axle to
peek at the gears?


From the miata.net Garage:

(Q)How do you identify Torsen's without dissasembly?

(A)The Torsen won't always turn both wheels when you turn the
driveshaft, sometime if they are cold they will. One way is to take out
the fill plug to see the Torsen gears which is hard to do because of the
angle. Another way is to attempt to turn both half shafts in the same
direction at the same time (tranny in neutral), can't be done with a
Torsen. The foolproof way is to pull the stub axle on the type 1 or the


Does turning the wheels differ than turning the half shafts? Aren't
they directly connected?

drive axle on the type two. If you don't see a bar and can see directly
thru the diff. it is a Torsen. If there is a bar, (spider gears) it's an
open.

Or you could phone Mazda with the VIN and they'll tell you how it came
out of the factory. The only '96 Miatas without Torsens were base and
power steering package models, plus all automatics.


My car has power steering and windows.

Car je vai m'acheter une 323 1.6 turbo si tout se passe bien... et si elle a trop de rouille a faire, je me prend une tite mx pour y greffé le b6t... mai sans auto-bloc
